The Balanced Brain by Camilla Nord explores the science behind mental health and wellbeing. It discusses how the brain processes pleasure, pain, motivation, and learning in ways that construct our mental state.

The book covers topics like the brain's reward system, prediction errors, resilience, the effects of chronic pain and inflammation on mood, the gut-brain axis, and more. It aims to provide a neuroscientific framework for understanding what contributes to mental health versus illness.

Nord explains proposed causes of conditions like depression and addiction in terms of disrupted brain processes. She also surveys various methods to improve mental health, from drugs to therapy to brain stimulation. Ultimately, the book argues for a personalized approach that targets specific biological factors underlying an individual's mental health.

In the 1700s, Benjamin Franklin observed that electrically stimulating paralyzed patients provided temporary improvements in symptoms, which he believed was partly due to placebo effect. Meanwhile in Britain, some patients experienced successful electrical treatment for conditions like paralysis. Modern explanations suggest patients with functional disorders may have been more likely to recover from such treatments than patients with permanent damage like stroke.

Electrical brain stimulation is still used today for mental health treatment, usually targeting underactive brain regions related to mood. Techniques like transcranial magnetic and electrical stimulation can improve mood in some patients with depression, though results vary widely. Some newer approaches give concentrated stimulation sessions daily, leading to symptom reductions for over 90% of patients in one study. Most stimulation is tried in patients who haven't responded to other treatments. While beneficial for some, invasive deep brain stimulation has had controversy over side effects.

Stimulation aims to induce plasticity-related brain cell changes rather than directly sparking activity. Over repeated mild sessions, cumulative effects may remain. But stimulation depends on each person's initial brain activity. People respond better if the targeted brain region already has closer-to-normal functioning pre-treatment. Monitoring ongoing activity could allow personalized levels of stimulation based on current brain state rather than a one-size-fits-all dose. While promising, existing methods can't yet target all the deep brain areas relevant in mental illness. Future techniques may achieve this non-invasively.

Though tempting to try to enhance healthy brains too, home electrical stimulation self-experiments predominantly rely on placebo-based anecdotes, not evidence. Scientific studies show more subtle or inconsistent cognition/mood improvements in healthy people. Risks like skin burns from unsafe DIY setups also exist. Research protocols are safer ways to try new interventions. In mental health, systematically targeting underlying processes - not diagnostic labels - with quantitative measures and appropriate treatments tailored for individuals will likely enable better future outcomes.
